Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497478, here are decompositions:

  • 19 + 2147497459 = 2147497478
  • 31 + 2147497447 = 2147497478
  • 67 + 2147497411 = 2147497478
  • 157 + 2147497321 = 2147497478
  • 241 + 2147497237 = 2147497478
  • 277 + 2147497201 = 2147497478
  • 337 + 2147497141 = 2147497478
  • 397 + 2147497081 = 2147497478

Showing the first eight; more decompositions exist.
